dummy_thread_fn(9)

💫 dummy_thread_fn(9) 💫

okay so bestie, welcome to the Kernel API Manual 🎀 — this is the page for dummy_thread_fn, and yes the name is a whole mood but she's lowkey doing important work, iykyk 💅

---

✨ NAME ✨

dummy_thread_fn — the dummy thread function, no cap 🫶

---

🌸 SYNOPSIS 🌸

irqreturn_t dummy_thread_fn (s32 irq , void *data );

like, that's the whole vibe. two args, one return, iconic 💖

---

🦋 ARGUMENTS 🦋

• irq — the IRQ number for this SPI Master ⭐ literally just the number of the interrupt we're talking about, bestie
• data — the structure for SPI Master controller davinci_spi 🍓 that's the lil payload that comes along for the ride

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this function exists to satisfy the request_threaded_irq API, so that the irq handler gets called in interrupt context. that's it, that's the job, and honestly? she ate 💅✨

ngl this one is not the main character of the file — she's the support beam, the hype girl, the "yes queen the API requires a threaded handler so here I am" energy 👑
